Ultra violet light affects many people, and several experiments may be done to either support or disapprove the hypothesis. Approval of the hypothesis forms a theory that people who are highly exposed to ultra violet light have higher chances of getting skin cancer. Theories on some scientific approach may serve as sources for theories. Observation of people's behavior may lead to development of hypothesis. This includes looking at how people dress during certain times or what they do at certain times of the year. Results obtained over a research or experiment may lead to development of a theory. Experience of the scientists in their work may be a source of hypothesis and theory. Many things happen around that nobody can explain them scientifically. The scientists come with a hypothesis about something and do numerous tests and observations to know how some things happen Eberhardt, 2003()
Role of hypothesis and theory
A theory helps expand our knowledge about information which seems to be obvious. The way in which a research will be done, the manner of conducting investigations and the research subject fully depend on the hypothesis and theory. A theory functions to direct the researchers towards interpreting how results of a certain study were achieved. It is also used to identify the cause of the results. Theories and hypothesis allow researchers to make predictions that are testable. They also help to mould the way people see the world and allows for the formation of principles about certain observations...
One of the most important roles of the hypothesis is to give direction to the research study being undertaken. It provides a framework through which results from the study are organized. A theory can be used to craft null hypothesis. These can be either proved or disapproved by the results obtained after a research Dembo & Peres, 1994()
The relationship between a hypothesis and a theory is that, hypothesis is a speculative guess that needs to be tested. Positive results of the research are accepted this forms the theory. Hypothesis makes predictions about certain specific circumstances while theories predict general terms of events. One of the steps of developing a theory is testing a hypothesis. Verification of the hypothesis forms the basis of developing a theory. Results of a hypothesis can be used in supporting, modifying or rejecting the basic theory Eberhardt, 2003()
